WARNING
• Risk of death in case of interrupted protective conductor!
– The protective grounding conductor (yellow-green) must not be interrupted,
neither inside nor outside of the device.
– Due to the high leakage current, operation is only permitted with a second
protective grounding conductor.
– The insulation of the protective conductor must never be damaged or
removed.
• Risk of death from connecting power supply units in series!
Contact voltages of greater than 25 V AC or 60 V DC are not permissible.
Coming into contact with voltages of greater than 50 V AC or 120 V DC
may be fatal.
–
Do not connect voltage sources in series.
• Risk of death due to electric shock!
Protect the outputs of the power supply units (output sockets/terminals) and
cables connected to them from direct contact.
–
Use only cables with adequate insulation and electric strength.
– Use safety sockets with fully shrouded contact points.
WARNING
Danger of electric shock
